Re: Django for desktop app development

2018-09-09 Thread Gerald Brown

I have created something similar to this. My setup is a 2 system
IntrAnet ( not Internet). One system is being used as a web server
running Nginx & Django with a Mariadb database. I also had to install a
wireless router. The server system is using the Django Admin system as
there are only 2 users.

From your description this could be system with one server and many
clients connecting to it if they are in range of the router as in my
case the client is just using Firefox web browser to connect to the server.

Does your school have WiFi available? If it does then this would be a
snap to setup with the Django server.

Good luck.

Re: models.py => Mandatory to create tables?

There should be a models.py file under each of your applications.

I tried, in this file, to import a model located somewhere else, but

Re: Django Generic Date Views

2018-08-09 Thread Gerald Brown

One thing I discovered is that I had the line for the url.py file in my 
top level url.py.  I moved it to myapp/url.p but still same 404 error, 
however no longer get the "has no attribute" error


How do I call this view?  Tried from the browser 
"http://127.0.0.1:8000/today/; and I get "__init__() takes 1 positional 
argument but 2 were given" error.


Tried "http://127.0.0.1:8000/visit/today/; and I get 404 error.

In the line "queryset = Visit.objects.all()" won't that select all of 
the records in the database when I only want the records for today which 
I then use to create a reportlab pdf file? Prior to trying to use these 
generic date views I was able to generate the file but only for the 
current date.


Are there any more suggestions?

TIA...

What I tried was the TodayArchiveView by following the docs. When I enter
http://127.0.0.1:8000/admin/visit/today/ in my browser I get a 404 error

The code in my views.py file is:
class PaymentTodayArchiveView(TodayArchiveView):This is exactly as it is in my code and also in the docs except I 
changed Article to Payment.

 vi = Visit.objects.all()I changed vi to queryset and it made NO difference.
 date_field = "visit_date"

The code in my URLS.py file is:
path('today/', PaymentTodayArchiveView, name="today"),

In the docs is says ".as_view()" should be added to
PaymentTodayArchiveView. When I add that I get "AttributeError: 'function'
object has no attribute 'as_view'" error.

This exception indicates that you didn't define
PaymentTodayArchiveView as a class, but rather as a function (which is
not consistent with the code you pasted above). As long as
PaymentTodayArchiveView is defined as a subclass of TodayArchiveView,
like in your snippet, you should be able to call ``as_view`` on it.

So yes, using ``PaymentTodayArchiveView.as_view()`` in your URL config
would be correct, as long as the definition of PaymentTodayArchiveView
is correct.

And regarding the name (``queryset`` vs. ``vi``) – the point of using
generic views is that the default implementation of the view supplies
most functionality. Most of the time, you're able to configure what
objects the view operates on by setting certain class attributes in
your customized subclasses. In this case, all of the generic date
views by default look at the ``queryset`` class attribute when they
want to read objects from the database, not ``vi``, which is why you'd
typically use that name in your subclass.

Good luck,

Michal

Django Generic Date Views

2018-08-08 Thread Gerald Brown

Greetings:

Tonight I discovered something at 
https://docs.djangoproject.com/en/2.1/ref/class-based-views/generic-date-based/ 
that I thought is just what I am looking for.  The only problem is I can't 
get them to work.

They are designed to present views by Year, Month, Week, Day, Today or 
specific Date.

If anyone has experience using them I would be interested in how it works 
for you.

Thanks.

Re: Django ORM aggregate Sum function on foreign key

This is how I finally solved my problem!!!

The following is a copy of my ORM statement:

 Visit.objects.filter(visit_date = mydate).aggregate(total =
Sum('visit_payment'))
{'total': Decimal('27')}
 This total is the total of the foreign key ids.  9 records each
with a key of 3 = 9 x 3 = 27

The way I solved this problem is to put another variable in the
loop where I was printing the records to Reportlab PDF file and I
incremented this variable with the value that was being printed. 
What was being printed was the value from the look-up table so I
was able to get a Sum from that.

Here is the code of how I did it: vi =
Visit.objects.filter(visit_date = mydate);  vip = 0; for v in vi:;
vi_pay = str(v.visit_payment); vip += int(vi_pay)

Here is how the Reportlab is built: Also in the same loop as above
I have the lines:  vi_pat = str(v.patient); pa1.drawString(x, y,
str(vi_pat)); pa1.drawString(x + 175, y, str(vi_pay))

Each of these are on a separate line in my code.

Hopefully this will help anyone with similar problems.

*Subject:* Django ORM aggregate Sum function on foreign key

Greetings:

I am having a problem using the above function.

In my table I have a field payment that is a foreign key to a
payment table.

When I try to use aggregate(sum('payment')) it gives me the sum
of the foreign key, not the value from the payment table.

Currently I have 9 records in my test DB each one has a foreign
key of 3 so I get a sum of 27 not 2,250 that I should be getting.

This table also has a foreign key to the customer table and it
returns the customer not the foreign key number.

The thought I had was to make that foreign key an integer field
and then the user would have to enter a number instead of
selecting it from a list, prone to operator errors,

Any ideas on how I can get the correct totals using ORM.

Thanks

How to pass variable dates to a ORM query

2018-08-06 Thread Gerald Brown

I have a Django/Python function that creates a Reportab PDF file based on 
the current date.  Works GOOD. Now I want to pass any date to that function 
and have it create a PDF based on the new date.

I tried creating  another function that generates the date (yesterday) but 
I am not able to pass the generated date to the first function.

Any ideas on how to do this???

Re: Django ORM aggregate Sum function on foreign key

2018-08-06 Thread Gerald Brown


This is how I finally solved my problem!!!

The following is a copy of my ORM statement:

 Visit.objects.filter(visit_date = mydate).aggregate(total = 
Sum('visit_payment'))

{'total': Decimal('27')}
 This total is the total of the foreign key ids.  9 records each with a 
key of 3 = 9 x 3 = 27


The way I solved this problem is to put another variable in the loop 
where I was printing the records to Reportlab PDF file and I incremented 
this variable with the value that was being printed. What was being 
printed was the value from the look-up table so I was able to get a Sum 
from that.


Here is the code of how I did it: vi = Visit.objects.filter(visit_date = 
mydate);  vip = 0; for v in vi:; vi_pay = str(v.visit_payment); vip += 
int(vi_pay)


Here is how the Reportlab is built: Also in the same loop as above I 
have the lines:  vi_pat = str(v.patient); pa1.drawString(x, y, 
str(vi_pat)); pa1.drawString(x + 175, y, str(vi_pay))


Each of these are on a separate line in my code.

Hopefully this will help anyone with similar problems.

Re: [Question] Django 2 - how to sum values based on filter and group by Year-Month

2018-07-27 Thread Gerald Brown

I am having a similar problem where I want to get the total (SUM) of 
about 20 - 30 items in a current day.  I can get the list of customers 
names and payments in a html table but so far haven't been able to get 
the SUM of those payments.  I have tried using Django ORM AGGREGATE 
SUM('integer field') but I am not able to get the results.


I haven't tried grouping yet in my project but will probably have to in 
the near future.  I think it is possible to group by week & month and 
then get a sum of those groups.  MariaDB has a function "MONTH" and " 
WEEKOFYEAR" which I hope will help with the grouping.  One problem that 
I have is that in my customer table I have a ForeignKey link to a 
Payment_amount table so the user can look up the payment amount instead 
of typing it in where an extra/less zero could be entered.


One web site that might offer some suggestions on solving your/my 
problem is: 
https://simpleisbetterthancomplex.com/tutorial/2016/12/06/how-to-create-group-by-queries.html. 
This site has a lot of posts relating to Django.


Good luck & I would be interested in how you solved this problem.

I need to Sum() the values filtering it with

{'sum_before_last_month_day': *60*},
 {'year-month': '2018-02'}, {'sum_before_month_day_one': *60*},

 {'year-month': '2018-03'}, {'sum_before_month_day_one': *70*},

So far I manage to sum values and group by month:

Re: learn dijango

2018-07-26 Thread Gerald Brown

The best way to learn Django is to jump in and start using it. If you
have problems there are many tutorials and web sites (including this
one) to provide help and support.

IMHO, a teacher CANNOT teach a student, all they can do is HELP the
student learn.

Re: How to automatically fill out an auto increment number in form field?

2018-07-23 Thread Gerald Brown

From 
"https://docs.djangoproject.com/en/2.0/topics/db/models/#automatic-primary-key-fields;, 
it has a further definition of automatic primary key fields.  In your 
model just add "(primary_key=True)" to po_number field.



On Tuesday, 24 July, 2018 07:54 AM, Michael MacIntosh wrote:


Hi,

Aren't you looking for the AutoField?

https://docs.djangoproject.com/en/2.0/ref/models/fields/#autofield

It will automatically increment based on each record added to the table.


As an aside, the problem you are having is that in python, the first 
argument to a class is a reference to the instance of that class.  In 
C this is often called a context.  In C++ and Java it would be like 
the `this` pointer.  So you wouldn't generally pass "self" to a class 
member.


Hope that helps!

You gave up too early. I don't know why it's ranked all the way on the right,
but this is defenitely stable and maintained and has a very good architecture:

Re: Good up-to-date Django report builder addons

2018-07-22 Thread Gerald Brown

I went to that site but sorry to say was UNABLE to find anything I could 
use as most are OUTDATED, written in Python 2.? ,Alpha or Beta versions 
that have not been updated in many years. 

I did find one on another site called i-net Clear Reports that has a FREE 
report designer similar to Crystal Reports that creates reports with a 
*.rpt extension.  

The only problem is in order to use those reports a person has to spend 
US$2,000 - US$5,000 or more for their report server application.  That is a 
bit steep for my wallet as a 1 person FOOS Django shop developing for a 2 
person client shop.

The report I need to design is a simple 3 column report with a totals 
summary at the bottom.

Again thanks for your info.

Have a look at pyenv . Relying on

Good up-to-date Django report builder addons

2018-07-20 Thread Gerald Brown

Does anyone know of any *GOOD, UP-TO-DATE* Django report builder add-ons?  

I was just working with Appy and discovered it was built with Python 2.? 
and I am using Python3.6.5. so I was getting a ton of errors.  Even though 
the last release in Pypi was in April 2018 they are still using Python 2.?

My client wants to create a daily report of customer spending.  The report 
should be simple to build as it consists of only 3 columns and a total at 
the bottom.  I want it to report by daily, weekly, monthly and yearly where 
the first will be a detailed report and the other 3 would be summary 
reports.

Many decades ago I used Crystal Reports but have not found anything similar 
for Django.  If anyone knows of this or something similar please let me 
know.

Thank you in advance!!!

You need a command after the "manage.py" like manage.py runserver, or

Re: Django foreign-key cannot assign must be a instance

2018-07-17 Thread Gerald Brown

The way I do it is backwards from what you are doing.  I.E. I make the 
models first and then use ./manage.py makemigrations & ./manage.py 
migrate.  This way Django creates the tables AND the FK Indexes, which I 
think may be missing on your setup.  Now that you have the models try 
running the above commands.


Hope this helps.

Re: How is MySQL syntax for a table changed if I had a ManyToManyField?

2018-07-14 Thread Gerald Brown

When looking at my database it has the 3rd table for the ManyToMany with 
the following:


1. ID auto-generated,

2. Table1.ID

3. Table2.ID.

All fields will be integers.

The 3rd table will be named Table1_Table2 or something like that.

I noticed in your code below that you do not have an ID field on any 
table.  I believe this is required for M2M tables.  Django 
makemigrations & migrate will generate this for you if not defined in 
the model.  Django will also create the third table for you with 
makemigrations/migrate so no need to create it by hand.


What were the problems you were having with makemigrations/migrate?  It 
is supposed to create the tables for all apps in your project but you 
can also specify only 1 app if you want to.


Hope this helps.

I'm a bit stuck on how to get these two to play together nicely.
I'm not sure if it's a django project configuration, an apache
httpd.conf problem, or a wamp issue. I'm wondering if someone has
experience with this issue and could point me in the right
direction for how to use django, but continue to use localhost or
myipxxx/ to access our non-django wamp sites.

Thank you,
Bob

Re: help

2018-07-06 Thread Gerald Brown

At https://docs.djangoproject.com/en/2.0/ref/models/fields/ it lists a 
list of various options, and Protect is one of the options so, yes you 
are correct.  However PROTECT prevents that record from being deleted so 
you might want to use CASCADE instead of PROTECT.

Re: Django split screen

2018-06-29 Thread Gerald Brown

Julio*,*

Thanks for the quick reply.

I have not worked with templates yet so that will be a new field for me
to explore.

On Friday, 29 June, 2018 09:41 PM, Julio Biason wrote:

Hi Gerald,

You can't "split" the screen because Django is simply a way to
retrieve data from a database and send HTML to the browser.

You can, however, load the history and create a form and send both to
the template, which will display both side by side (or one on to the
top of the other, or whatever).

All you have to do is create a view that loads the history and create
a form object and send both to a template that knows how to display both.

2018-06-04 Thread Gerald Brown

I have been using ./manage.py shell for awhile and now all of a sudden it 
has stopped working with the error "AttributeError: 'property' object has 
no attribute '__dict__'".  I get the same error with anything I enter after 
the ./manage.py (i.e. runserver, dbshell, etc)

I think it might have to do with something I added to my requirements.txt 
file.

Does anyone know of a way other than committing out the requirements.txt 
one-by-one on how to solve this problem?

Thanks.

Re: ImportError : cannot import name include

2018-05-18 Thread Gerald Brown

Another option to get the current version of Django is to create a file
called requirements.txt. In this file enter django on a line, and other
requirements on other lines. You can also specify a specific version
with django==1.11 or any other version by changing the number after the
==. If this is left off then the latest version will be installed. Then
in your virtual environment enter the command 'pip install -r
requirements.txt'. This will download and install everything that is in
the requirements.txt. This file will grow as you enter more requirements.

Your problem is right here:

> django-admin --version 1.11.13

You are using Django 1.11. The documentation you are using refers to a
newer version of Django, version 2.0.

Use the right documentation for your version of Django:

https://docs.djangoproject.com/en/1.11/

You are seeing this specific error because in Django 2.0, you can
write "from django.urls import include", while in Django 1.11, you
have to write "from django.conf.urls import include".

Note that using Debian packages, you won't get the latest version of
Django (or any other Python packages). You might want to consider
installing the latest version with pip.

https://docs.djangoproject.com/en/2.0/topics/install/#installing-official-release

Hope that helps,
Daniel

Re: Problem with debug = True/False

2018-05-18 Thread Gerald Brown

My site now looks the same in Development and Production.  I think why this 
is happening is that I ran ./manage.py collectstatic awhile ago,  So if you 
are getting weird formatting when DEBUG = False try running ./manage.py 
collectstatic and see if that solves your problem!!!

SQL select statements to Django ORM

2018-05-12 Thread Gerald Brown

As I have said previously, I am new to Django ORM so I would like to know 
howto/find reference to Django ORM Query to the following SQL Select 
statements:

1. From Mariadb. 

SELECT name, date_of_birth, *TIMESTAMPDIFF(YEAR,date_of_birth,'2014-08-02'/or 
curdate())* AS age FROM some table.

2. General SQL statement
SELECT field1, field2, field10 from some table

3. How to see all of the data from those statements which SQL shows me. 

I have read (several times) the documentation @ 
https://docs.djangoproject.com/en/2.0/topics/db/queries/. They show numerous 
examples of Queries but none of them show the results from those queries.

When I do get results to show ONLY the fields that are in my __str__ statement 
show up. If I add additional fields they also
show up in my FK list, which I don't want.

Thanks for all previous help from this group.

Re: Django Queries

2018-05-12 Thread Gerald Brown

I was getting the same as you are as I had just first_name & last_name 
set in the "def __str__(self)".  I added a couple of more fields to that 
statement but they are still not showing up even after running a 
makemigration which says "No Change"

I tried "p.address" but it gave me an error message, (which I don't 
remember) as I did not know about the "[]"s.  Now if I do 
"p.[0].address" it gives me the address. Also if I do "p[0].town" it 
show me the town name, which is in another table and is a FK to that table.

Like I said in my original message, I am just starting to use Django 
Queries so there is a lot to learn so I thank you for your assistance.

On Saturday, 12 May, 2018 01:34 PM, Mark Phillips wrote:
Please provide the exact output you are seeing. It may be that the

For example, when I run this query on the command line for my model 
Document,

, ]>

I get a QuerySet with 4 entries, as there are 4 rows/records in the 
Document table. All the fields are there, just not shown. The __str__ 
method in the Document model returns the title of the document, which 
is what is shown above for each Document in the QuerySet. I am 
guessing but your People table probably defines the __str__ method to 
return the first and last name.

I can look at one of the returned rows like this:

>>> d=Document.objects.all()
>>> d[0]

>>> d[0].document_id
2
>>> d[0].title
'a new title 2'
>>> d[0].description
'a new description 2'
>>> d[0].document_state
1
>>> d[0].storage_file_name

>>>

title, document_id, description, and storage_file_name are all fields 
defined in the model for Document (along with others).

Read the django documentation about models and queries for more 
information.

Thanks for your reply.

My model consists of the following:

id, first_name, last_name, middle_initial, contact_num, address, town(FK
to Town table), date_of_birth, occupation(FK to Occupation table), email
& gender. The Django query returns ONLY first_name & last_name.

I run migrations after any changes to any models. The database has the
same fields that are shown.

BTW, the query is being run after running ./manage.py shell.

Hi,

That is the way it should be if you look in the documentation:
https://docs.djangoproject.com/en/2.0/howto/static-files/

Serving the files

In addition to these configuration steps, you’ll also need to 
actually serve the static files.


During development, if you use|django.contrib.staticfiles| 
<https://docs.djangoproject.com/en/2.0/ref/contrib/staticfiles/#module-django.contrib.staticfiles>, 
this will be done automatically by|runserver| 
<https://docs.djangoproject.com/en/2.0/ref/django-admin/#django-admin-runserver>when|DEBUG| 
<https://docs.djangoproject.com/en/2.0/ref/settings/#std:setting-DEBUG>is 
set to|True|(see|django.contrib.staticfiles.views.serve()| 
<https://docs.djangoproject.com/en/2.0/ref/contrib/staticfiles/#django.contrib.staticfiles.views.serve>).


This method is*grossly inefficient*and probably*insecure*, so it 
is*unsuitable for production*.


SeeDeploying static files 
<https://docs.djangoproject.com/en/2.0/howto/static-files/deployment/>for 
proper strategies to serve static files in production environments.



So it is exactly like gunicorn - because you need to serve your 
static files from a webbserver instead of from django itself.


That's why it is failing.

What you could do (although I don't recommend it) - it to manually 
add the static files serving to your urls.py file. See:

https://docs.djangoproject.com/en/2.0/howto/static-files/#serving-static-files-during-development

This should be fine for a developer environment - but nothing else.

Re: Problem with debug = True/False

Thanks for the info. I will check it out.  I am still in development so 
it will be awhile before I need it.

Hi,

That is the way it should be if you look in the documentation:
https://docs.djangoproject.com/en/2.0/howto/static-files/

Serving the files

In addition to these configuration steps, you’ll also need to actually 
serve the static files.


During development, if you use|django.contrib.staticfiles| 
<https://docs.djangoproject.com/en/2.0/ref/contrib/staticfiles/#module-django.contrib.staticfiles>, 
this will be done automatically by|runserver| 
<https://docs.djangoproject.com/en/2.0/ref/django-admin/#django-admin-runserver>when|DEBUG| 
<https://docs.djangoproject.com/en/2.0/ref/settings/#std:setting-DEBUG>is 
set to|True|(see|django.contrib.staticfiles.views.serve()| 
<https://docs.djangoproject.com/en/2.0/ref/contrib/staticfiles/#django.contrib.staticfiles.views.serve>).


This method is*grossly inefficient*and probably*insecure*, so it 
is*unsuitable for production*.


SeeDeploying static files 
<https://docs.djangoproject.com/en/2.0/howto/static-files/deployment/>for 
proper strategies to serve static files in production environments.



So it is exactly like gunicorn - because you need to serve your static 
files from a webbserver instead of from django itself.


That's why it is failing.

What you could do (although I don't recommend it) - it to manually add 
the static files serving to your urls.py file. See:

https://docs.djangoproject.com/en/2.0/howto/static-files/#serving-static-files-during-development

This should be fine for a developer environment - but nothing else.

Andréas

Re: Getting error in migrate

2018-05-09 Thread Gerald Brown

Some times you will need to run ./manage.py makemigrations  
and then ./manage.py migrate .

By including the  it will only makemigration and migrate for a 
single application instead of for all of the applications.

I have found that this helps as I too was having problems with 
makemigration and migrate.

Also I found it is shorter to leave off the python and use ./manage.py 
.  Saves a few keystrokes.

I tried that too but it kept giving an error about Key constraints. That

Re: django makemigrations not working

Yes. I dropped it and then recreated it.

Then ran "makemigrations" & "migrate". Migrate is now giving me a lot of 
errors.


Funny that all of the errors that show up are in lines that contain 
"**/site-packages/django/**", NOT in any lines of MY code.

Re: OperationalError

2018-05-03 Thread Gerald Brown

Been there. Done that. Many times!!! Still can't find the field list
that it is complaining about.

What is really weird is that the same code runs on 2 other computers
without any errors.

That looks like merge conflicts with Git. You’ll want to fix those
up, not just by deleting those lines, but by verifying the code does
what you want it to.

You may want to just delete all of your migrations files and start
anew if they’re not important to you.

Thanks for the reply.

I have done the makemigrations/migrate numerous times. Each time it
says there is an error in the previous migration file so I have to
comment out most of the file. I then just deleted all of the self
generated migration files and started fresh.

I was also getting some weird characters in my files like ">>>>random
letters & numbers. I deleted all of those & ran the migrations again.

The weird thing is that now when I click on the link it says "unknown
column telephone in field list", previously it was first_name that was
unknown.

I have this application running on a "similar" computer and it has
*NO* problems with this area so maybe there are some other
applications running that cause the problem even though this one is in
a virtualenv.

Have you tried "pip install django" without the "== 2.0.5". I think that 
if you do not specify a version pip will install the latest version.

Re: DJANGO Migrations from older version : South db

If you have the original models.py files just run "python manage.py
makemigrations" and then "python manage.py migrate".

OperationalError

2018-05-01 Thread Gerald Brown

I have a Django application that I am having problems with.  In the Admin 
page I have 3 sections, ABC, DEF & XYZ. Each has 1 option to "Add/Change".  
In 2 of them when I click on the option it works fine. The third gives me 
the following error "



*1054, "Unknown column 'xyz_xyz.first_name' in "field list"*The Exception 
location is: 
*/home/medrec1/.virtualenvs/medrecproj/lib/python3.5/site-packages/*MySQLdb
*/connections.py in query, line 277*

On another system (both running the same code) I was also getting a different 
error also in *site-packages/MySQLdb* but I was
able correct that by installing 2 DEV packages and then installing MySQLClient, 
which I also did on this computer.  The other
system does NOT give this error.

Any ideas, suggestions, solutions on how to solve this error and any other 
errors in the Django code?

Thanks.

I had replied to Daniel Roseman instead of to the users group as I am

AttributeError at /admin/login/

2018-04-30 Thread Gerald Brown

I am getting the following error when I TRY to log in to my site
"AttributeError at /admin/login/ 

'datetime.datetime' object has no attribute 'split'"

This looks like a Django bug as it is in the Admin module and is NOT related to 
any of my code.

Does anyone have any idea why this is happening???

Thanks.

3 Django errors

I have 3 laptops set up supposedly running the same code but each one gives
me a different error message. See attached file for an explanation of the
problems.

Each of the 3 systems are supposedly running the same code.

Thanks for any thoughts, ideas, or *SOLUTIONS* for the listed problems.

Have a look at this article:

It might do what you are trying to do.  There are also a lot of other posts

Re: When deleting field in models admin form not updating.

2018-03-31 Thread Gerald Brown

I had run migrations several times.  The last migration said "Nothing 
changed.".  However today when I rebooted my system the fields were gone so 
I guess the reboot took care of them.

Thanks for your reply.

Re: Connecting django to postgresql database

2017-06-02 Thread Gerald Brown

When you run "python manage.py.migrate" are you in the same directory as 
the "manage.py" file?  Also I always run "python manage.py makemigrations" 
before running the "migrate" command.

Hope this helps.

Re: No installed app with label 'province'.

2017-02-11 Thread Gerald Brown

Finally solved the problem!!!
At the end of each Model definition I had added:
class Meta:
managed = True
db_table = 'refer'
app_label = 'Refer'

I then commented those lines out and then the program worked like it 
should. I saw another post where they had put those variables as part of an 
"options" statement.

I was getting other errors when I did not have the "app_label" line so that 
is why I added that.

Here is the INSTALLED_APPS: "INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
#'django.contrib.sites',
 'sumedrec',
]"

Here is the admin.py: "from django.contrib import admin
from .models import Patient, Visits

# Register your models here.

mymodels = [ Patient, Visits]
admin.site.register(mymodels)"

No installed app with label 'province'.

2017-02-07 Thread Gerald Brown

I have just started an app on Ubuntu 16.04 Server using Python 3.5 and 
Django 1.10.5.

When I do "@admin.register(Province)" in my admin.py file I get the error 
that is the subject of this post.

Of course there is NO app with label of 'province' as that is the label of 
a 'Model'.

Why is Django trying to register an app instead of the Model?

Thanks,

Gerald

Ignore previous post!!!

2017-02-07 Thread Gerald Brown

You can ignore my previous post as I *think* I discovered my problem.

I had 2 admin.py files and the second one was giving me the error...

Re: Django documentation tutorial part 1

2017-02-07 Thread Gerald Brown

Have you tried using "127.0.0.1" instead of "localhost"?  I had a similar 
problem when I used "localhost"
